1 John 2:3-11 Revised Standard Version Catholic Edition (RSVCE)
3 And by this we may be sure that we know him, if we keep his commandments.[a] 4 He who says “I know him” but disobeys his commandments is a liar, and the truth is not in him; 5 but whoever keeps his word, in him truly love for God is perfected. By this we may be sure that we are in him: 6 he who says he abides in him ought to walk in the same way in which he walked.
A New Commandment
7 Beloved, I am writing you no new commandment, but an old commandment which you had from the beginning; the old commandment is the word which you have heard. 8 Yet I am writing you a new commandment, which is true in him and in you, because[b] the darkness is passing away and the true light is already shining. 9 He who says he is in the light and hates his brother is in the darkness still. 10 He who loves his brother abides in the light, and in it[c] there is no cause for stumbling. 11 But he who hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.
1 John 2:3-11 New International Version (NIV)
Love and Hatred for Fellow Believers
3 We know that we have come to know him if we keep his commands. 4 Whoever says, “I know him,” but does not do what he commands is a liar, and the truth is not in that person. 5 But if anyone obeys his word, love for God[a] is truly made complete in them. This is how we know we are in him: 6 Whoever claims to live in him must live as Jesus did.
7 Dear friends, I am not writing you a new command but an old one, which you have had since the beginning. This old command is the message you have heard. 8 Yet I am writing you a new command; its truth is seen in him and in you, because the darkness is passing and the true light is already shining.
9 Anyone who claims to be in the light but hates a brother or sister[b] is still in the darkness. 10 Anyone who loves their brother and sister[c] lives in the light, and there is nothing in them to make them stumble. 11 But anyone who hates a brother or sister is in the darkness and walks around in the darkness. They do not know where they are going, because the darkness has blinded them.
Luke 2:22-35 Revised Standard Version Catholic Edition (RSVCE)
Jesus Is Presented in the Temple
22 And when the time came for their purification according to the law of Moses, they brought him up to Jerusalem to present him to the Lord 23 (as it is written in the law of the Lord, “Every male that opens the womb shall be called holy to the Lord”) 24 and to offer a sacrifice according to what is said in the law of the Lord, “a pair of turtledoves, or two young pigeons.” 25 Now there was a man in Jerusalem, whose name was Simeon, and this man was righteous and devout, looking for the consolation of Israel, and the Holy Spirit was upon him. 26 And it had been revealed to him by the Holy Spirit that he should not see death before he had seen the Lord’s Christ. 27 And inspired by the Spirit[a] he came into the temple; and when the parents brought in the child Jesus, to do for him according to the custom of the law, 28 he took him up in his arms and blessed God and said,
29 “Lord, now lettest thou thy servant depart in peace,
33 And his father and his mother marveled at what was said about him; 34 and Simeon blessed them and said to Mary his mother,
“Behold, this child is set for the fall[b] and rising of many in Israel,
Luke 2:22-35 New International Version (NIV)
Jesus Presented in the Temple
22 When the time came for the purification rites required by the Law of Moses, Joseph and Mary took him to Jerusalem to present him to the Lord 23 (as it is written in the Law of the Lord, “Every firstborn male is to be consecrated to the Lord”[a]), 24 and to offer a sacrifice in keeping with what is said in the Law of the Lord: “a pair of doves or two young pigeons.”[b]
25 Now there was a man in Jerusalem called Simeon, who was righteous and devout. He was waiting for the consolation of Israel, and the Holy Spirit was on him. 26 It had been revealed to him by the Holy Spirit that he would not die before he had seen the Lord’s Messiah. 27 Moved by the Spirit, he went into the temple courts. When the parents brought in the child Jesus to do for him what the custom of the Law required, 28 Simeon took him in his arms and praised God, saying:
29 “Sovereign Lord, as you have promised,
33 The child’s father and mother marveled at what was said about him. 34 Then Simeon blessed them and said to Mary, his mother: “This child is destined to cause the falling and rising of many in Israel, and to be a sign that will be spoken against, 35 so that the thoughts of many hearts will be revealed. And a sword will pierce your own soul too.”
